The Top Chinese NPI solutions Partner
Verification Phase of NPI Solutions
The verification stage of NPI solutions is a crucial risk control step. Before mass production, we’ll confirm the design feasibility, material properties, and process stability. We will strictly follow the product requirements to conduct rigorous verification of the DFM output results, geometric tolerances, and functional performance. We will identify potential deviations between design and manufacturing in advance to avoid affecting the delivery time.
We use CNC machining, vacuum casting, 3D printing or other low cost & easy handle process to create physical prototypes, and complete assembly compatibility, mechanical durability, and actual working environment tests. We optimize all steps and smooth start of the subsequent production.
Why does the verification phase matter?
Without a customized New Product Introduction (NPI) verification process, design teams often struggle with:
Our all-in-one solution addresses the common challenges of traditional NPI processes:
- Poor coordination between design, testing, and production
- Multiple suppliers causing inconsistent quality
- CAD-perfect, shop-floor-impossible
- No expert support for materials and design
- Difficulty balancing cost, speed, and accuracy
- Weak data tracking in quality control
- Unstandardized testing leading to repeated failures
- Delayed Time-to-Market
- Seamless collaboration
- Single point of responsibility: One team manages everything from design to delivery
- Expert guidance throughout material selection, design optimization, and process advice all in one place
- Optimized trade-offs：Data-driven decisions to find the best balance
- Full traceability – Every step documented, every result trackable
- Standardized testing system

FAQs About Verification Phase of NPI Solutions
What is NPI verification, and why do I need it?
NPI (New Product Introduction) verification is a structured review that happens before we cut any material. We analyze your drawing, material choice, tolerances, and inspection requirements to confirm everything is manufacturable—and cost-effective.
Why it matters: It catches problems early, when they’re cheap to fix, rather than during production, when they’re expensive and time-consuming.
What is your quality control system?
We operate under a rigorous Quality Management System (QMS) aligned with ISO standards. Our 5 Steps QC process is including IQC (Incoming Quality Control) , FQC (Final Quality Control) , OQC (Outgoing Quality Control) for routine production.
QE (Quality Engineering) / CAPA (Corrective and Preventive Actions) implemented throughout the entire product lifecycle, especially during the post-sale stage, to drive continuous improvement. Simply speaking 100% inspection before shipment to ensure zero defects.
What kind of quality assurance or warranty do you offer on orders?
One of the reasons engineers purchase from RPD is that we take on all the risks for you. We guarantee you’ll love what you get. Not happy with it? We’ll either redo it or give you a full refund. Your purchase is completely risk-free.
Which kind of file formats can I send for tooling& production?
We accept STEP, IGES, STL, DWG, DXF, and other common CAD formats.
Can you review my drawing before I commit to a quote?
Absolutely, that’s necessary step before send you official quote. We offer a free drawing review as part of our NPI verification process. We’ll flag:
Features that are difficult or impossible to machine
GD&T callouts that may drive up cost unnecessarily
Material recommendations that could improve performance or reduce lead time.
